[Bug 121897] On resume, knetworkmanager tries to ifup eth0 without a link

[Michael Blakeley]

Public bug reported:

Binary package hint: knetworkmanager

This might be a network-manager bug- I'm not sure how the flow of
control works, between those two.

When I resume my laptop (hp nc6400) from suspend-to-RAM, I see
knetworkmanager's "connecting" icon (spinning gear) and a mouseover
indicates that it's trying to connect on eth0. But eth0 has no link, per
the ethtool output above, so the connection eventually falls back to a
self-assigned DHCP address.

The previous version of knetworkmanager (or network-manager) didn't do
this. It used to recognize that eth0 didn't have a link, and fall back
to eth1 (my wifi interface). I'd like to have that behavior back.
